`The present invention relates to an improved form of fire-crackers, which substantially comprises two series of crackers aXialj ly set up against each other with their fused ends leaving a small space between them, each series being composed of two or more units arranged laterally side by side and the fuse of each unit of both series being kept in contact with one another within and those of the upper units projecting out of said space, which is completely covered with a strip of paper so as to keep the crackers in position. The object of the invention is to provide a new type of crackers in which any desired number of them can be fired without mis-firing.

In the crackers according to this invention all the paper-string fuses are inclosed in a closed space formed between the fuse ends of the crackers of both series, so that they are completely protected from damage and also kept free from the moisture of the outer air, which is very important to prevent their missing lire. Besides, the main fuse can be dispensed with and no connection of each fuse is needed with the arrangement of the invention.

A practical application of the subject of the invention will now be fully described in referenceto the accompanying drawing, in which Fig. 1 is a plan showing part of paper removed and Fig. 2 is a longitudinal section on line A-B of Fig. l. `Each series is composed of two or more crackers l l arranged laterally side by side two series are in their turn arranged axially with their fused ends set up against each other` leaving a small space 2, which is hermetically closed by pasting a strip of paper wider than the width of said space so as to keep all crackers of both series in position.
